gamous flowers, two anatropous ovules, and opposite leaves. Helicia, 
though very close to Xylomelum, differs in its fleshy indehiscent fruit. 
Lambertia has regular flowers formed like those of certain Grevilleas ; 
but it is distinguished by its two ovules being nearly orthotropous 
descending, the micropyle still looking downwards; and we may 
remark that this is a constant character in the order, the causes of 
which we have investigated elsewhere.’ The micropyle is always 
inferior, whether the ovules are ascending and more or less completely 
anatropous, or orthotropous or nearly so, and consequently descend- 
ing; the base of the ovary is surrounded by four leaves, alternate with 
the perianth-leaves. Roupala approaches Lambertia by its quite 
orthotropous ovule; its fruit is a follicle opening longitudinally. 
Andripetalum has the flowers of Roupala with a slightly fleshy 
drupaceous indehiscent fruit. Guevina has the same orthotropous 
ovules, and a nearly dry indehiscent fruit ; but the flower is slightly 
irregular, the perianth being inserted obliquely on the receptacle, with 
the two anterior leaves attached lower down than the posterior pair.
